摘　　要：随着生态城市、生态居住区及环境建设的发展,景观水体已经成为城市建设中不可缺少的组成部分。如何科学合理地配置水生植物,已经成为亟需解决的问题。本研究于2015年3—12月对重庆26个都市区景观水体以及3个近郊区湿地公园的水生植物进行了样地调查,其中都市区景观水体选取14个典型代表,通过景观质量指标和景观协调性指标对其进行景观评价,同时将相关指标与近郊区湿地公园进行对比。结果表明:研究区域内共有水生植物42种,分属于22科,主要以湿生植物和挺水植物为主,浮水和沉水植物应用较少。在都市区景观水体中,仅重庆大学和大渡口公园的时序多样性指数略高于观音塘湿地公园和爱莲湖湿地公园,其余景观水体指标均明显低于3个近郊区湿地公园。其中6个景观水体水生植物配置综合评价等级为中等及以上,8个景观水体的景观评价等级为差或极差。基于此,本研究分析了在景观水体水生植物应用过程中出现的问题,为进一步构建健康的景观水系统提供科学的理论依据和技术支撑。Landscape water body has become an essential part during the rapid development of ecological city,ecological dwellings and environmental constructions.Accordingly,effective confi guration of aquatic plants within these water bodies becomes an urgent problem.FromMarch to December in2015,a sampling plot investigation was conducted on the aquatic plantsin26landscape water bodies in the metropolitan area,as well as three in the suburban areasin Chongqing.Among the26landscape water bodies,14representative ones were selectedfor fi nal analyses.For each of the14representative water bodies,landscape quality index andlandscape coordination index were calculated to evaluate their aquatic plants configurations.In this study,a total of42aquatic plant species that belonging to22families were recorded.The majority of the species were of hygrophytes and emergent plants,with a few presences offl oating and submerged plants.All the index of the14water bodies in the metropolitan areawere significantly lower than those calculated for the three in the suburban area(exceptingfor the timing diversity index,which was slightly higher in the Chongqing University andDadukou Park than that in the Guanyintang Wetland Park and Lotus Lake Wetland Park).Theaquatic plants confi guration of six water bodies were at the good or medium level,eight water bodies were at poor or the worst levels.Based on the analyses of the confi gurations of aquatic plants in landscape water bodies,this study will provide further support for the construction of healthier landscape water bodies.
